Abstract:
(EN) A machine tool is configured so that: a first frequency band comprising the main shaft characteristic vibration frequency and a second frequency band comprising the mechanical structure characteristic vibration frequency are set; thresholds are stored for each of the set frequency bands; vibration components are extracted for each of the frequency bands from the output of a vibration sensor; and when the vibration amplitude exceeds a threshold in either of the frequency bands, an alarm is sounded.
(FR) L'invention concerne une machine-outil qui est conçue de telle sorte que : une première bande de fréquence comprenant la fréquence de vibration caractéristique d'arbre principal et une seconde bande de fréquence comprenant la fréquence de vibration caractéristique de structure mécanique sont définies ; des seuils sont stockés pour chacune des bandes de fréquence définies ; les composantes de vibration sont extraites pour chacune des bandes de fréquence à partir de la sortie d'un capteur de vibration ; et lorsque l'amplitude de vibration dépasse un seuil dans l'une ou l'autre des bandes de fréquence, une alarme se fait entendre.
(JA) 工作機械において、主軸系の固有振動数を含む第1の周波数帯域と、機械構造体系の固有振動数を含む第2の周波数帯域とを設定し、設定された各周波数帯域毎に閾値を記憶し、振動センサからの出力から、各周波数帯域毎の振動成分を抽出し、何れかの周波数帯域で振動の振幅が閾値を超えた場合に警告するようにした。
